To all 'whom it 'may concern: v

Beit known that we, GUsTAV G. GRAMM land AUGUsTUs F. Trinite, citizensof the United States, both residing at ll'orceste'r,

in the vcounty of `Worcester and State of Massachusetts, have invented anew and useful Brush, of which the following is a Specification.

` This invention relates to brushes, and par ployed for the huinan body.y

The principalobjects of the invention are to provide a --eonstruotionwhich will be entirely sanitary, which will have features 5 renderingthe brush capable of being cleansed and disinfected' in 'a very simpleand convenient manner; to provide a construction in which the holder forthe bristles will have smooth surfaces and a minimum nuiuber ofirregularities so that there no places where foreign matter can gather;to provide improved meansfor fastening the removable parts together; andother iin- ,roved features'of holder itself.

Further objects and advantages of the invention will appear hereinafter.

`Reference is to be had to the accompanyinedrawings, in whiclilligure 1is a side view of a tooth-brush shown'ig oneforin in which thisinvention may he carried out; Fig. 2 isla similar view showing the threedetachable parts separated; l1ig. 3 is a plan of the bristle holderremoved from the other elements; Fig. 4 is a plan of a hairebrushlpartly Abroken away to show the top of the bristle holder, andinvolving certain inodieations; Fig. 5 is a side view'tliereof showingthe parts sepa- 0 rated.; is a side view of a shavingbrush partly insection showing another forni of the invention; and Fig. 7 of thebristle holder thereof.

Referring first to the .irst three figures, 5 the brush in this fornicomprises it flat bristle holder l() consisting of a plate of anon-corrodible alloy which will not be attacked by any of the ordinarydisinfeoting solutions adapted to be employed for clean- 0 ing thebrush. This holder oriplate is provided vwith substantially uniformplane top and bottoni surfaces so that there will be no unnecessaryprotuberances or depressions on or lect. nthe top surface are a seriesof shalwhich are y eniwill be few or..

construction in the bristle silver so is a plan in which foreign inattercan collow grooves 11 adapted to receive the wirer or .other fasteningmaterial with which the*v bristles 12 -are` fastened 1n position. lnA

order to fasten the bristles these grooves are provided with smallperforations 13 which are enlarged below tov receive the bristles7A thepart of these perforations shown in'lligf 3 being smaller to receive thewire or other fastening ineans. It will beunderstood of course thatthese grooves can be filled over the fastening thread or wire with anyV`inaterial which will protect the fasteningde-lvice and present asmooth upper surface,

but we prefer tonuse a wire which initselfy is not capable of beingattacked by the anti?.

septic solutions. These' grooves are parallel' and longitudinal, and the'fastening incluis preferably extends along thciu continuously? from oneto the other in a well understood inanncr. 'Between these grooves areinter gralicontiiiuous walls 14 having surfacesflush with the topsurface of the plato or holder, and providedwith perforations.-15`through which a liquidcan bey passed or. forced to insure the cleaningof the bristles and the surfaces belowwhieh collie between the bristles.Located at the end of the bristle holder is 'a projection 1G 'which is-shown in this instance` as screw-threadedand riveted by means of arivet 17 to thev plate. This projection may he of Gcrnian as to resistthe attacks ofliquid' disinfectants, and have strength enough to keepits threads intact-.in use. On the/bach of this bristle holder islocated acapxor cover 20. This preferably is forinedof. a' sheet ofGerman silver Aflat on the top to lit the top of the bristle holder andreinforce itj and bent down at the sides and ends so as to engage thesides and. ends of the bristle holder. lt may be held thereon 'by thercsiliency of its sides and ends which preferably tit thc platefriction' light', but we profer to fasten it by means of a handle 2l..For this puigpose the'cap or cover is pio vided with a slot 29. throughwhich the projection 1G passes, and tho end of the handle .is providedwith a scrcwthreadcd openiii'g 23 for receiving the projection. Aroundthis opening is a shoulder 2l which, when the handle is screwed up onthe projection, engages the end of the cap or cover on both sides oftheslot and elanips it firinly to the end of the bristle holding plate.

The cap or cover 42 is provided i shown as fixed by a screw45 to the German grooves 11 .are oblique elongated perfora- .moreefficiently to permit the circulation of -the cap or cover 32 is formedsubstantially .This can be done without, interfering with infectingacids. The bristle holding plate Figs/: and 5.,/ the bristle-holdingplate 30 1 is ofcsubstantially the same construction as that describedexcept that between the tions l31 between the grooves. vThey serveliquid through the brush back. In this case like the cap or cover 20,except` that it is not provided withA a slot in the end, but is madeintegral 'with'th'e handle 33, both, f these parts preferably beingformed f Gr'er-V man silver or some other sheet material. In this case`the cap or 4cover ils secured to the plate or holder 32 by a sufcientlytight fit of its surrounding walls 34. In these two forms thebristleholder or plate extends to the back of the capor cover and fits snugi-yso as to leave no space in which dirt capi collect, thus making thebrush thorouglislj sanitary and rigid.

In Figs. 6 and 7 the same principle is ap lied to a shavin brush. In,this case thel bristle holder or p ate 40 is shown as formed accordingto the principles shown in Fig. 3,- but the projection 4l thereon is notscrewwith an L-sha ed slot 43 fonreceiving'the projection eti forholding the parts in position, although it will be understood that theprinciples slfown in Fig;l 5 can be employed in this case. Here also thehandle 445 isA ysilver cap 42, and as `being located on the baglriif itinstead of at the;` side or endy as in the other forms illustrated.

The manner'of using the brush will be readily understood. The partsbeing assembled and the brush having been used, it is cleaned byseparatingv the parts, placing the .bristle-holder in an antisepticsolution, bolllng itor treating it in any desired Way.

thefhandle or back, which would not be the case if these parts werefixed to the bristle holder, because usually they are made of materialwhich is attacked by ordinary disis of a metallic 'alloy which is notattacked by such disinfectants', and whichA will stand boiling watere Itwill be understood from what` has beenA shown and described that thisinvention may be carried out in many "ways, and may be 'applied tovarious t pes of brushes;

While we have ilustrated and described certain forms of the inventionand certain applications thereof, -we are aware, that many modicatonscan be made therein -by any erson skilled in the art Without departingomy the scope of the invention as expressed iIi the wish to be limitedto all the forms or details of construction shown, but

What we do claim isz- 1. `In a brush, the combination of a bristleholder having substantially uniform flat top andI bottom surfaces andhaving perforations theaethrough, and a fastenin means thereon, aremovableca or cover or said holder,

device for securing it to said fastening means on the holder and forsecuring the cover thereon. W I Y 2. In a brush, the combination of ametallic non-corrodible bristle holder having a uniform lower surface,and provided with a screw threaded projection at one end, a uhollowmetal cap or cover ada ted to cover the back and sides of said holer,ha'ving a slot for receiving said projection, and a handle having ascrew lthreaded socket for receiving said projection,and a shoulderaround the end of the socket for engaging the end of the cover at thesides of said slot, whereby the cover will be clamped to the holder whenthe handle is screwed up.

In testimony whereof we have hereunto set our hands, in the presence oftwo 'subscribing witnesses. i
